Crate to_method

A utility micro-crate for using Into and TryInto more ergonomically.

It exposes a To extension trait with a .to() method and .try_to() method which you can use to invoke Into::into and TryInto while specifying the target type and without having to abandon method-call syntax.

Being a micro-crate, it tries to be as nice of a dependency as possible and has:

• No dependencies of its own
• No feature flags
• No build.rs
• #![no_std]
• #![forbid(unsafe_code)]

Regular Into usage

let x : u8 = 5;

// The type parameter is on `Into`, not on `Into::into`,
// so we need to do it like this:
let y = Into::<u16>::into(x);

// Depending on context, inference can make this work though:
let z : u32 = y.into();

With To

use to_method::To as _;

let x : u8 = 5;

// The type parameter is on the `to` method, so this works:
let y = x.to::<u16>();

// And you can still rely on inference as well:
let z : u32 = y.to();

TryInto

The same mechanism works for the TryInto trait via the try_to method:

use core::convert::TryInto;


let x : u16 = 5;

// The type parameter is on `Into`, not on `Into::into`,
// so we need to do it like this:
let y = TryInto::<u8>::try_into(x)?;

// Depending on context, inference can make this work though:
let z : u8 = y.try_into()?;

compared to:

use core::convert::TryInto;


use to_method::To as _;

let x : u16 = 5;

// The type parameter is on the `to` method, so this works:
let y = x.try_to::<u8>()?;

// And you can still rely on inference as well:
let z : u8 = y.try_to()?;
